income of the lord... what do you mean by that?
eg.. you have before lord loses position 4 estates in the region:
lord's estate
steward's estate
some knight's estate
wildlands/vacant.
when the lord loses his lordship (eg.. captured..) he retains his estate..
so what does a lord's income mean? lord's cut? wildlands?
it would be extremely silly to let the steward take the lord's cut. vacant/wildlands might just about be justified...
anyway... it would have to be a very lucky steward for the lord not to be re-appointed / new one appointed/elected and get a tax in the meanwhile..
